  • Publication number: 20140311949
    Abstract: A method for removing sulfur, nitrogen or metals from an oil feedstock. The method involves reacting the oil feedstock with an alkali metal and a radical capping substance. The alkali metal reacts with the metal, sulfur or nitrogen content to form one or more inorganic products and the radical capping substance reacts with the carbon and hydrogen content to form a hydrocarbon phase. The inorganic products may then be separated out from the hydrocarbon phase.

The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

    Abstract: Provided are a method for producing a super-low sulfur gas oil blending component or a super-low sulfur gas oil composition having a sulfur content of less than 5 mass ppm, under relatively mild conditions, without greatly increasing the hydrogen consumption and without remarkably decreasing the aromatic content; and a super-low sulfur gas oil composition having a sulfur content of less than 5 mass ppm which exhibits a high heating value, is excellent in fuel economy and output power, and is free from an adverse effect on a sealing rubber member or the like used in the fuel injection system and thus does not cause the leakage of a fuel. A method for producing a super-low sulfur gas oil blending component or a super-low sulfur gas oil composition having a sulfur content of less than 5 mass ppm is also disclosed.

  • Patent number: 7906013
    Abstract: A process is provided to produce an ultra low sulfur diesel with less than about 10 ppm sulfur using a two-phase or liquid-phase continuous reaction zone to convert a diesel boiling range distillate preferably obtained from a mild hydrocracking unit. In one aspect, the diesel boiling range distillate is introduced once-through to the liquid-phase continuous reaction zone over-saturated with hydrogen in an amount effective so that the liquid phase remains substantially saturated with hydrogen throughout the reaction zone as the reactions proceed.

  • Patent number: 7871512
    Abstract: In crude oil fractions, fossil fuels, and organic liquids in general in which it is desirable to reduce the levels of sulfur-containing and nitrogen-containing components, the process reduces the level of these compounds via the application of heat, an oxidizing agent and, preferably, sonic energy. The invention is performed either as a continuous process or a batch process, and may further include optional steps of centrifugation or hydrodesulfurization.

  • Patent number: 7824541
    Abstract: Described is a catalyst and process useful in the hydrodesulfurization of a distillate feedstock to manufacture a low-sulfur distillate product. The catalyst comprises a calcined mixture of inorganic oxide material, a high concentration of a molybdenum component, and a high concentration of a Group VIII metal component. The mixture that is calcined to form the calcined mixture comprises molybdenum trioxide, a Group VIII metal compound, and an inorganic oxide material. The catalyst is made by mixing the aforementioned starting materials and forming therefrom an agglomerate that is calcined to yield the calcined mixture that may be used as the catalyst or catalyst precursor.

  • Patent number: 7763164
    Abstract: This invention focuses on the specialized catalyst and/or additive for lower FCCU gasoline and diesel blendstock component sulfur content. This invention utilizes a specified ratio of the transition metal oxides of cobalt and molybdenum to accomplish gasoline and diesel blendstock sulfur reduction. This is accomplished by minimizing sulfur compound formation in the FCCU riser. The cobalt and molybdenum oxides in the presence of H2S from cracked organic sulfur compounds are converted to metal sulfides. A portion of the overall sulfur reduction in the gasoline and diesel blendstock occurs emitted NOx also is reduced.

  • Patent number: 7708956
    Abstract: A method and an apparatus for removing sulfur hydrocarbon compounds from a naphtha stream and for simultaneously removing sulfur hydrocarbon compounds from two streams is described. A separator vessel having a top, a bottom, a primary feed inlet and a co-feed inlet is disposed vertically above the primary feed inlet. The separator vessel further includes a catalyst bed disposed between the co-feed inlet and the top. A primary feed stream comprising sulfur hydrocarbon compounds is delivered through the effluent inlet and a vaporized co-feed stream that also comprises sulfur hydrocarbon compounds is delivered through the co-feed inlet. Vaporized sulfur hydrocarbon compounds from the primary feed stream with the vaporized co-feed stream pass upwardly through the desulfurization catalyst bed. Sulfur hydrocarbon compounds from both primary feed and co-feed stream are at least partially converted to hydrogen sulfide and non-sulfur containing hydrocarbons in the catalyst bed.
